We investigate their algebraic properties, classify them into C1, C2, D, and P-types, and analyze their matrix representations. Numerical examples illustrate key findings, highlighting both their theoretical structure and potential areas of application. Key findings are demonstrated with numerical examples, emphasizing their structural importance and their uses.eninfo:eu-repo/semantics/openAccessComplex numbersHybrid numbersMatrix representationsPauli matricesArticle10.1016/j.kjs.2025.100528531WOS:0016597479000012-s2.0-105026490273Q3Q2
